more particularly to 'the class of adjustable holders or brackets for glass ware for use with a glass cutting machine.

The primary object of the invention is the i `provision of a holder or bracket of this characterwherein the articles of glass ware can be" firmly clamped therein Aand held in position -relative to thecutting or grinding element for the scoring of the` glass article longitudinally thereof or in straight courses, and such scoring willbe uniformly spaced apart to give a neat and ornamental individuality of the larticle of glass ware when finished.

2 Another object `ofthe invention is the provision of `a holder or` bracket of thischaror grinder-with accuracy and -enabling the scoring of the glass ware for the cutting `thereof with despatch so that the glass ware will present uniform scoring throughout the area` of itsu surface worked upon.

A further object of the invention is the provision of a holder or bracket of this character wherein the parts thereof are readily adjustable so that it can be accurately set, for the convenient holding ofthe glass ware to be operatedupon for the 'scoring or cutting thereof to give ornamental effect theretoin "the finished article.

A still furtherobject-of the invention is theprovision ofa holder or bracketJ ofthis character which is extremely simple in `construction, 'thoroughly efficient-` in its purpose,

In the accompanying drawings: Figure 1 isa fragmentary side elevation of a glass ware grinder showing the bracket constructed in" accordance with the invention applied and holding in position an article of glass ware; Fig. 2 is an enlarged fragmentary vertical longitudinal sectional view through the holder; Fig. 3 is a vertical transverse sectional view through one `of the joints of the holder; Fig. 4 is a sectional view through another of the joints of the holder; Fig. 5 is anend view of the work clamp; Fig. 6 is a fragmentary enlarged vertical longitudinal sectional view `through the work clamp showing in detail the ratchet dog and head.

Similar reference characters indicate corresponding` parts throughout the several views of the drawings.

\ `Referring to the drawings in detail,` A 4designates a grinderwhich is of any approved for1n,and is rotatably supportedin a frame B, asusual, the grinder beingdriven :from any suitablesource ofmotive power and is merely shown to illustrate the application and use of the work holder or bracket hereinafter fully described. Arranged within the frame B is the trough C which isof the usual construction, and on one end of `which is an inclined board or plate 10 for the mounting of the work holder or bracket hereinafter fully described.V The work holder or bracket comprises a base 11 which is fastened tothe board or plate 10 in any suitable manner and is formed with a centrally socketed boss 11 having threaded therein a setfscrew 19. for the fastening in `the socketed boss ofthe upright or post 16, the part 15 of the joint being formed `with a1 circular hub 17 which fits within a correspondingly shaped socket 18 formed in the part,14,\and upassed centrally through -these parts 14 land `15 is a pivot 19 which rotatably connects the same together. The hub 17 `engaged inthe s'cket 18 will prevent any play of the parts14 and 15, yet permits free rotation ofthe said parts. Ad-
